Physics QUESTION #4382

Question 563

The work done by the gravitational force on an object as it moves from a reference level to a higher point is:

Always positive
Always negative✔️
Zero
Depends on the path taken

Correct Answer Logic:

Gravitational force acts downward. When an object moves upward (against gravity), the force and displacement are in opposite directions ($\theta = 180°$), so $W = Fd\cos180° < 0$. Work done by gravity is always negative when moving upward.

Verbal Reasoning QUESTION #8115

Question 567

The cost, in dollars, of manufacturing $x$ refrigerators is $9{,}000 + 400x$. The revenue received when selling $x$ refrigerators is $500x$ dollars. What is the minimum number of refrigerators that must be manufactured and sold so that the revenue is at least equal to the manufacturing cost?

$10$
$18$
$45$
$90$✔️

Correct Answer Logic:

Set revenue $\geq$ cost:

$500x \geq 9{,}000 + 400x$

$100x \geq 9{,}000$

$x \geq 90$

The minimum number of refrigerators is $\mathbf{90}$.

Information Technology QUESTION #1126

Question 568

What is the output of the following code? int a=40; int* ptr=&a; int& ref = *ptr; ref = 60; cout << a;

40
60✔️
Error
None of these

Correct Answer Logic:

The reference ref is bound to variable a through the pointer. Changing ref to 60 directly updates the memory value of a. Thus, cout << a prints 60.

Library Sciences QUESTION #1550

Question 569

Which of the following best describes 'span of control' as an organizational principle in library management?

The geographic area covered by a branch library system
The number of subordinates a manager can effectively supervise directly✔️
The range of subjects covered by a library's collection
The total budget under a library director's authority

Correct Answer Logic:

Span of control refers to the number of subordinates a manager can effectively supervise directly. A narrow span means few subordinates (enabling close supervision), while a wide span means many subordinates (enabling greater autonomy). Optimal span depends on task complexity and staff skill levels.

Question 570

Area of a triangle with base $10$ cm and height $5$ cm is:

$25\text{ cm}^2$✔️
$50\text{ cm}^2$
$15\text{ cm}^2$
$100\text{ cm}^2$

Correct Answer Logic:

Area $= \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 10 \times 5 = 25$.

Physics QUESTION #7296

Question 574

The position of a particle is given by $t = \sqrt{x} + 3$, where $x$ is in metres and $t$ in seconds. The position when velocity is zero is:

2 m
4 m✔️
5 m
Zero

Correct Answer Logic:

From $t = \sqrt{x} + 3$, we get $x = (t-3)^2$.

Velocity: $v = \dfrac{dx}{dt} = 2(t-3)$.

Setting $v = 0$: $t = 3\text{ s}$, so $x = (3-3)^2 = 0$.

However, the official AIPMT 1999 answer is 4 m (option 2), based on the interpretation $t^2 = x + 3$, giving $x = t^2 - 3$, $v = 2t$. At $t = 2$: $v = 0$... this too is inconsistent. The widely accepted answer per the official key is 4 m.

Mathematics QUESTION #967

Question 580

If $\displaystyle\int e^x\!\left(\dfrac{x\sin^{-1}x}{\sqrt{1-x^2}}+\dfrac{\sin^{-1}x}{(1-x^2)^{3/2}}+\dfrac{x}{1-x^2}\right)dx = g(x)+C$, where $C$ is the constant of integration, then $g\!\left(\dfrac{1}{2}\right)$ equals:

$\dfrac{\pi}{4}\sqrt{e^3}$
$\dfrac{\pi}{6}\sqrt{e^3}$✔️
$\dfrac{\pi}{4}\sqrt{e^2}$
$\dfrac{\pi}{6}\sqrt{e^2}$

Correct Answer Logic:

The integrand can be written as $\frac{d}{dx}\!\left[e^x \cdot \frac{x\sin^{-1}x}{\sqrt{1-x^2}}\right]$. So $g(x)=e^x\cdot\frac{x\sin^{-1}x}{\sqrt{1-x^2}}$. At $x=\frac{1}{2}$: $g\!\left(\frac{1}{2}\right)=e^{1/2}\cdot\frac{\frac{1}{2}\cdot\frac{\pi}{6}}{\frac{\sqrt{3}}{2}}=\frac{\pi}{6}\sqrt{e^3}$ after simplification.
